Anthropic told prospective investors on Wednesday, October 14, that its third-quarter revenue reached $16.8 billion, a 45% increase from the previous quarter, according to Reuters. The figure, shared at a pre-IPO meeting in San Francisco, gives investors a fresh measure of the Claude maker’s growth as it prepares for a possible public listing. The company also said it was profitable on an adjusted basis during the quarter, Reuters reported, citing an investor who attended.
Revenue climbed from $4.7 billion to $16.8 billion
The quarterly figures show revenue rising from $4.7 billion in the first quarter to $11.6 billion in the second, then to $16.8 billion in the third. The latest increase added $5.2 billion over the prior quarter. The Information reported that third-quarter revenue was more than 3.6 times Anthropic’s total revenue for all of 2025.
Growth remained substantial, but its pace slowed. Revenue had risen by more than 140% between the first and second quarters, The Information reported, compared with 45% in the third. That shift matters to prospective shareholders weighing not only the scale of Anthropic’s sales, but whether its exceptional expansion can continue as the company grows.
Adjusted profitability carries a qualification
Anthropic told attendees it was profitable on an adjusted basis in the third quarter, Reuters reported. The Information put the adjusted operating margin at 11%, citing a person briefed on the figures. Those measures are not interchangeable with a full account of net income: “adjusted” results depend on which expenses the company excludes, and the reports do not provide a reconciliation of the figure.
The distinction matters because revenue growth alone does not establish that a company can cover the costs of developing and running its models. Reuters described Anthropic’s investor event as part of preparations for an IPO and framed the figures against the substantial costs facing AI developers. The reported adjusted result offers investors a positive signal, but the information made public through these accounts does not show the full expense picture.
A private briefing, not a public earnings report
The $16.8 billion figure came from a meeting with prospective investors, rather than a public earnings release. Reuters attributed the revenue numbers to an attendee; its report also said Anthropic told the group about adjusted profitability. The Information separately reported the 11% adjusted operating margin and compared the latest growth rate with the prior quarter’s faster rise.
That sourcing shapes what the figures can establish: they reflect what the company presented to potential IPO investors, as recounted by people briefed on the meeting. They do not, on their own, provide the detailed disclosures investors would use to assess costs and earnings on a consistent basis. The revenue series is clear; the accounting behind adjusted profitability remains less fully described in the reports.
Growth is strong; its direction is the IPO question
For Anthropic, the third-quarter numbers put rapid expansion and a slower growth rate in the same investor pitch. The company’s reported sales are much higher than earlier in the year, while the step-down in quarterly growth shows why a single headline figure cannot settle questions about future performance. The adjusted profitability claim adds another favorable data point, but it is not a substitute for details on what the adjustment excludes.
Reuters said Anthropic’s listing is expected to come before rival OpenAI’s public debut, making the company an early test of investor appetite for large AI developers. The concrete numbers from Wednesday’s briefing are $4.7 billion in first-quarter revenue, $11.6 billion in the second and $16.8 billion in the third.
